17.91

釋曰：二無心定得者，二無心定者，謂無想定、滅盡定也。此與諸業非俱有故，不為引因，但能為滿。得者，善惡得也，得與諸業非一果故，唯滿非引。除此二類，所餘善惡皆通引、滿。

Explanation: "The two mindless absorptions and acquisition": the two mindless absorptions are the absorption without conception and the absorption of cessation. Because these are not co-existent with any karma, they do not serve as projectile causes, but can only fulfill. "Acquisition" refers to wholesome and unwholesome acquisition. Because acquisition does not share the same fruit with karma, it only fulfills and does not project. Excluding these two classes, all remaining wholesome and unwholesome [phenomena] can both project and fulfill.
